Re: [Discuss-gnuradio] Bug Report

[Derek Kozel]

Hello Raj,

Bugs are tracked on the GitHub Issues system.
https://github.com/gnuradio/gnuradio/issues

Looking at the build guide there is no mention of scipy so that should get updated as needed. Also the pybombs recipes do not install scipy by default for GNU Radio.

Given that scipy isn't needed for the functionality, only the test, it may be nice to try and remove that dependency from the tests.

Thanks for the report!

Derek

I can't find a public bug tracker (is there one?), so here's a report.

GNURadio maint branch as of today (509330cfb6ad5b8b8787ba069b96ee35c5ac9c2d) on a fresh Ubuntu 16.04 install with gr-fec enabled fails the "make test" on all "qa_polar_*" tests. Upon looking into it with ctest -V, either the qa code or the polar module itself has a python dependency on scipy's optimization / rootfinding algorithms. However, the cmake process never checks for scipy, as far as I can tell.

How to reproduce:

Get a fresh Ubuntu 16.04 insall going

Install the prereqs to make gr-fec work

Build gnuradio and run "make test" to watch the failure

Use ctest -V -R polar_decoder_sc (for example) to see that scipy imports failing are the cause of the problem

Workaround: install scipy (apt-get install python-scipy on Ubuntu)

Proposed fix:

If gr-fec is enabled, cmake should check for scipy as a dependency. Sorry I don't have time to contribute a patch.
